It's such a tough call as to my favorite. The 24k's need new lenses, and Oakley finally shipped my new lenses after three months of backorder. But.. man, they're all so great!
Were the Ice a bit more rare than the rest? Seems like the BI and 24ks are the easiest to find, then the Ti's, but I haven't really seen any Ice lately.
I also guess I got lucky because I ordered some replacement BI and 24k lenses and only had to wait about 2 weeks of backorder
